Marketing. :] The CD devices, up to a given speed, can keep the data speed constant, as single speed CDs did (constant linear velocity of the medium). Above a given value, the data speed has to be varied with the radius (constant angular velocity of the medium). There are docs that talk about this, even some about what is the maximum speed before things go wrong (too much vibration, even damages), it is basic physics (linear and angular speeds in circular movement). So you will only get 40x at the outer part of the CD, when you are near MB # 600, for example. It happens with reading too, try a tool that gives you the actual KB output in a graph, and try to read a full CD from the begining to the end. You do not see CD devices above 52x or so, and none really meets that value until the end, they are always "# Speed (Max)" in the small print. What is more, it seems some (all? mine is faulty? :] ) drives even slow down when reaching the 650MB limit, like trying to avoid going out of the data. That seems to happen with a Plextor reader and 700MB media that has ~680MB used. The speed goes fine a lot of time, more and more as time passes, then slows a bit, goes up again, and a few secs later the read ends.
